How do I edit upside down text?
Infix does not deal with 180degree rotated text very well.
Please click anywhere on the page with the text or object tools,
Turn on text boundaries using View->Text->Boundaries
Then rotate the page by 180 degrees using Document->Pages->Rotate...
Then drag out a new text box around existing blocks of text that have not formed correctly.
Then choose Text->Text Box->Rebuild
Repeat this for each block of text that has not formed correctly (because it was upside down before you rotated the page).
Once fixed, export the document (Document->Translate->CAT Export...) and save the tagged version.
When you reload the translation you can rotate the page back again to its original rotation.
